Care of a rottie, I would say is make sure your train, train, train, never stop. Bring the rottie to obediance classes. They will teach you how to train it. People are afraid of these dogs, So having it be obedient will always work in your favor.
Whoever said you can't buy happiness, must have never owned a dog!!!!!!!!!!!
